Unable to reach the local server via domain settings, but accessible from the local IP address.
Unable to reach the local server via domain settings, but accessible from the local IP address.
I manage a Minecraft server on a different machine using No-IP for dynamic DNS. Previously, I could reach the server from my main PC with the domain name assigned locally. Recently, connections have stopped and I’m only getting local IP addresses. The problem seems to affect more than just these two devices. I’ve tried setting up another server on a separate computer and tested from yet another unique machine, but it still doesn’t work. This suggests an issue with your router configuration. Some people suggest editing host files, but that’s not a recommended approach for me since I’ve used this method before without any problems. Actions I’ve taken: confirmed external users can connect via domain name, checked port forwarding settings, ensured the public IP is current, verified NAT type, and adjusted network adapter settings to "hybrid." I’m really confused and would appreciate your guidance!
The server remains reachable both locally and remotely, yet you can’t connect using your No-IP domain. This suggests NAT Loopback is the cause. It’s a router configuration that controls whether LAN traffic can reach WAN interfaces. Toggling it should resolve the problem. If you don’t see this setting, other issues might be at play. Connecting via local IP seems problematic, especially if your computer moves around frequently.
Also keep in mind that NAT Loopback is a workaround that consumes router resources unnecessarily (since all traffic goes through the router on the LAN instead of directly to the server). I stopped using NAT Lookback once I accidentally drained the router’s capacity by downloading a file from my NAS through it. A more efficient alternative if your router supports it is setting up a DNS override that reports the local LAN IP address when accessed from within the network. Honestly, it’s simpler to just use the IP address, save it in your game, and pick it when connected to your LAN.
